The Brazilian Labour Party (, PTB) is a political party in Brazil founded in 1981 by Ivete Vargas, niece of President Getúlio Vargas. It claims the legacy of the historical PTB, although many historians reject this because the early version of PTB was a center-left party with wide support in the working class. It is the seventh largest political party in Brazil with more than a million affiliated as of 2022. Despite the name suggesting a left-leaning unionist labour party, the PTB was mostly a centrist party for most of its history, considered part of the Centrão, a bloc of parties without consistent ideological orientation which supports different sides of the political spectrum in order to gain political previleges. As such, they supported the presidency of Fernando Collor de Mello, Itamar Franco, Fernando Henrique Cardoso — all considered center-right — Luiz Inácio Lula da Silva and the first term of Dilma Rousseff — who were leftist presidents. Since the conservative wave in the 2010s, the party has shown strong support for the government of Jair Bolsonaro, presenting policies from a more right-wing angle, in addition to affiliating federal deputy Daniel Silveira, known for making references to AI-5.

After that PTB, along with every other Brazilian party, was banned. In 1979, the military dictatorship that had dismantled the historical PTB decided to revoke its legislation which enforced a two-party state. Soon thereafter, the social-democratic wing of the original PTB, led by Leonel Brizola, attempted to recreate the party, but the military government instead awarded the name to a group led by Ivete Vargas, niece of Getúlio Vargas, who became the president of the party. Many of her group were politicians who did not follow PTB's historical labourist ideology, conservatives and even former oppositors of the party. Leonel Brizola instead led his faction to found the Democratic Labour Party (PDT). This all but ensured that the PTB would abandon leftist politics, ultimately embracing centrist or slightly right-leaning politics. At the legislative
